Python Django在调试为false时为未知URL提供500而不是404

Django=2.1.x

Python=3.7.x

如果Debug为True，则返回404

如果Debug为False，则给出500错误

我的

project.url

urlpatterns = [
    path("admin/", admin.site.urls),
    path("", app1.views.log_in, name="log_in"),

当我

python manage.py运行服务器时，我点击了一个我知道不存在的URL（比如
http://project/randomtrash.php
）如果
DEBUG=True

如果
DEBUG=False
，则点击相同的URL将得到
500
，并显示
500.html

Django在debug=True时呈现调试页面，忽略404页面

请参见
这与
应用程序上下文
和
注册
上下文处理器有关

在这些测试中，他们使用了
请求
并解决了与之相反的问题（即
解析（request.path）.app_name
），而这些问题在
404
或其他错误上永远不会匹配，从而导致响应中出现
500
错误

目前，我已将这两个函数中的每一个都封装在它自己的简单if语句中：

if request.resolver_match:
    ...do stuff...

现在，所有错误都按预期正确呈现。
是的，这就是我知道它注册了404的原因。当我将其设置为False时，它给出了一个
500
错误，不再注册为404
